Utilising Biometrics for Transparent Authentication on Mobile Devices
Mobile devices have become a ubiquitous computing device, with over a third of the world’s population now owning a device. The nature of the device has expanded far beyond its original inception as a telephony device, now capable of accessing and storing a wide-variety of information. Given this increased access, the ability to effectively provide security has become increasingly important. Key to these is authentication of the user to the device.Karatzouni S, Clarke NL, Furnell SM
Unfortunately current authentication methods such as the PIN are found to be severely lacking in providing any level of security beyond initial point-of-entry, with the level of protection being provided here arguable insufficient. This paper proposes the application of biometric techniques in a transparent and non-intrusive fashion to enable continuous and user convenient authentication of the user. The proposed mechanisms seek to adapt current classification algorithms in a manner that trades off a small degree of security for larger improves in the robustness and user acceptance of the approach.
